Maryland’s experiment with taxing digital advertising collapsed not because courts are hostile to taxing technology, but because the statute fused speech controls, platform-specific targeting, and a global-receipts design that ran headlong into federal and constitutional limits; the result is refunds for major taxpayers and a cautionary blueprint for any state tempted to copy it.
The Short Version
- Maryland’s Digital Advertising Gross Revenues Tax has been voided in state tax court, with refunds ordered for Apple, Google, and Peacock TV.
- Earlier federal appellate litigation already struck the statute’s “pass-through” speech ban under the First Amendment, narrowing the law’s enforceable core.
- Challengers prevailed on multiple theories in state courts over time: Internet Tax Freedom Act (ITFA), Commerce Clause, and First Amendment defects.
- The episode demonstrates how digital-only gross receipts taxes that scale by global revenue invite constitutional risk and costly refund exposure.
What Maryland Tried To Do—and Why It Looked Different From Ordinary Sales Taxes
Enacted in 2021 and effective beginning in 2022, Maryland’s law taxed “annual gross revenues of a business derived from digital advertising services in the State,” but only if the taxpayer’s global annual gross revenues exceeded a $100 million threshold. Rates were graduated—topping out at 10 percent—based not on Maryland activity but on the advertiser’s worldwide receipts, and the base was gross rather than net income. In plain terms, the law targeted a narrow business model (digital advertising) and scaled the burden by company size measured globally, even as liability hinged on ads viewed in Maryland. That combination—platform-specific, gross-receipts, size-graduated, worldwide-revenue-referenced—distinguished the measure from familiar retail sales or corporate income taxes. Proponents framed it as a revenue source for education, with early projections near $250 million annually; actual collections landed well below that ambition, underscoring the volatility that accompanies novel tax bases.
One more design choice proved pivotal. Maryland barred taxpayers from passing the levy to customers “by means of a separate fee, surcharge, or line-item” and effectively from explaining any price change as attributable to the tax. That speech-facing provision was intended to keep the charge embedded in pricing, not showcased on an invoice. It became a constitutional tripwire.
The Litigation Arc: From Narrow First Amendment Defect to Full Invalidation and Refunds
The first significant federal decision arrived as a narrowing strike. In 2025, the U.S. Court of Appeals for the Fourth Circuit held that Maryland’s pass-through ban was a content-based restriction on speech in violation of the First Amendment. The panel did not take down the entire tax; it severed the disclosure gag and left the rest of the statute nominally intact pending further litigation. That posture—surgical invalidation of a speech provision—can tempt policymakers to declare victory because the “tax itself” survives. But it also erodes a core enforcement mechanism and signals deeper structural fragility.
Meanwhile, parallel state-court contests pressed broader theories: discrimination against electronic commerce under the federal Internet Tax Freedom Act (ITFA), Dormant Commerce Clause violations tied to the tax’s out-of-state focus and use of worldwide revenue gradations, and First Amendment flaws beyond the pass-through ban. In 2022, a Maryland circuit court struck the scheme on multiple grounds, including ITFA and the Commerce Clause—an early indication that the law’s basic architecture, not just its speech add-on, was at risk.
The denouement came in 2026 at the Maryland Tax Court. In refund actions brought by Apple, Google, and Peacock TV, the tribunal voided the tax and ordered the state to return amounts collected. That is a financial and legal judgment, not a symbolic one: refunds reverse the cash flow and crystallize the defects as applied to actual taxpayers rather than in the abstract. Coverage of the ruling emphasized that the tribunal found the law unlawful and unconstitutional, triggering repayment obligations to the prevailing companies.
Why These Theories Stuck: A Mechanism-Level Look at the Defects
Start with ITFA. Congress barred states from imposing taxes that discriminate against electronic commerce; a levy that singles out digital advertising—while analog or non-digital promotional channels remain untaxed—invites an ITFA challenge. Maryland’s design could be read to do exactly that: it isolated a digital delivery mode for a gross-receipts tax while not imposing a parallel burden on comparable non-digital advertising. Courts have been sensitive to such digital-only constructs, and practitioners consistently flagged ITFA risk for Maryland’s statute from the outset.
Now the Dormant Commerce Clause. States may not structure taxes that discriminate against or unduly burden interstate commerce. Using a taxpayer’s worldwide revenue to set a Maryland tax rate is an unusual move because it keys a Maryland burden to out-of-state (indeed global) economic scale. That feature can function like a tariff on size and extraterritorial activity rather than a neutral measure of in-state presence. Challengers stressed that the statute’s thresholds and rate brackets tilted the incidence toward large, predominantly out-of-state firms—precisely the sort of structural discrimination Commerce Clause doctrine disfavors.
Finally, speech. The Fourth Circuit’s ruling against the pass-through ban was unambiguous: government cannot prohibit a company from truthfully and separately communicating a tax’s impact on pricing. Retailers separate line items all the time; forbidding that speech content because it might shift public sentiment is not a permissible regulatory purpose. Once that provision fell, the law’s operative signals to market participants changed; companies could disclose and attribute price changes to the tax without fear of sanction, altering incidence and compliance dynamics in ways the Legislature had apparently tried to control.
Refunds and Fiscal Exposure: The Hidden Cost of Novel Tax Design
Refund litigation is not a sideshow; it is where financial reality catches up with legal ambition. Maryland faced roughly 20 taxpayer refund suits by 2024, with exposure compounding as statutory interest accrued. Commentators noted Maryland’s 9 percent per annum interest on certain refunds—a rate that can turn a contested $100 into $190 if the fight drags a decade. Multiply that across a base of large filers and you begin to see the policy cost of designing at the edge of constitutionality: each month of uncertainty is expensive, and the bill comes due if the law fails.
The 2026 Tax Court orders directing refunds to Apple, Google, and Peacock convert that theoretical exposure into concrete obligations, and they set practical expectations for similarly situated taxpayers. Even if appellate steps remain, the center of gravity has shifted from “first-in-the-nation innovation” to remediation and unwind.

How States Can Tax Digital Activity Without Repeating Maryland’s Errors
The takeaway is not that digital activity is untaxable. It is that form and neutrality matter. States have durable tools that travel well in court: sales and use taxes on in-state consumption of services, corporate income taxes with standard apportionment by sales in the state, and gross-receipts taxes that apply across broad categories rather than singling out a digital substrate. Three design disciplines reduce risk: avoid digital-only targeting where analog equivalents exist (to sidestep ITFA), reject rate schemes that hinge on global revenue (to avoid extraterritorial discrimination), and never regulate price messaging as a backdoor incidence fix (to stay clear of the First Amendment).
Policymakers should also build severability explicitly. If a statute relies on a controversial enforcement tool—such as a pass-through speech restriction—draft a clean severability clause and a back-up compliance framework that survives if the tool is struck. Maryland’s experience demonstrates how losing a “mere” provision undercuts the rest of the machinery; litigation then leverages that instability to reach the base tax itself.
Global Comparisons Don’t Rescue a Flawed State Statute
Advocates sometimes point to national digital services taxes, such as France’s DST, which have survived domestic constitutional review. That analogy misleads when applied to U.S. states. A sovereign nation is not bound by the U.S. Internet Tax Freedom Act; a U.S. state is. National governments also do not face our Dormant Commerce Clause constraints on discriminating against interstate commerce. The right comparison for a state is not Paris but Phoenix: state-level taxes must live inside federal supremacy and constitutional doctrines that have evolved to police state burdens on the national market. Maryland’s law, designed as a digital-only gross-receipts levy keyed to global size, was poorly situated on that terrain.
What This Means Going Forward—for States, Platforms, and Everyone Who Buys Ads
States still want a piece of the value created by targeted ads and platform intermediation. The lesson of Maryland’s reversal is to build that claim through neutral, technology-agnostic bases that tax in-state consumption or in-state apportioned income without singling out digital channels or calibrating rates by global scale. For platforms, the win is not a get-out-of-tax-free card; it is a reminder to separate speech rights from tax liabilities and to press ITFA and Commerce Clause arguments when statutes treat “digital” as a taxable proxy for “large and out-of-state.” For advertisers and consumers, greater price transparency returns—companies may line-item and explain government-imposed costs—and fewer surprise surcharges will be buried in opaque totals.
Maryland sought to harness a modern revenue engine to fund public goods. The engine it built, however, ran on parts that federal law and the Constitution don’t allow at the state level. Refunds are the predictable result of that mismatch. The durable path is less flashy: broad bases, neutral treatment, and speech left alone.
